Sarcocornia perennis has also been reported from the coasts of the northeastern United States, but most of these plants appear to be depauperate individuals of S. pacifica. However it is possible that some plants from New England are S. perennis, and further study is needed to determine the precise distinction between S. perennis and S. pacifica.
